Abstract
A method of controlling fuel delivery to an engine includes providing a fluid atomizer, a mechanically driven air compressor, a start up air source, and an air valve coupled between the mechanically driven air compressor and the start up air source, charging the start up air source, delivering compressed air from the start up air source to the fluid atomizer, providing an initial air/fluid mixture with the fluid atomizer, and operating the air valve to direct compressed air from the mechanically driven air compressor to the fluid atomizer.
Claims20
A method of controlling fluid delivery, comprising:
- providing a fluid atomizer, a mechanically driven air compressor and an air source;
- charging the air source with a volume of compressed air independent of the mechanically driven air compressor;
- delivering compressed air from the start up air source to the fluid atomizer;
- after delivering compressed air from the air source, delivering compressed air from the mechanically driven air compressor to the fluid atomizer.
A method of controlling air flow to a fluid atomizer, comprising:
- providing a scavenger valve, the scavenger valve being coupled in flow communication with a cylinder of an engine;
- opening the scavenger valve to collect compressed air during engine start cranking prior to starting the engine;
- delivering the compressed air from the scavenger valve to the fluid atomizer, the fluid atomizer operable to create an air/fuel mixture.
A method of starting an internal combustion engine, comprising:
- providing a fuel delivery system and a compressed air source;
- charging the compressed air source with compressed air from the engine prior to combusting fuel in the engine;
- providing a flow of the compressed air from the compressed air source to the fuel delivery system;
- creating a fuel/air mixture with the fuel delivery system;
- delivering the fuel/air mixture to a cylinder of the engine to start the engine.
